Application and January 21,1916. Serial ms. 73,320; a

Beit. known that I, WILLIAM W. HORN, a

' citizen of the United States of America, and

. has for its object to provide a simple and substantial structural formation and association of scaffold parts, whichwhen erected for use will afford a light, strong and rigid vertical post of the structure.

support for the workmen and material, and which when folded together will occupy a compact space for storage, transportation, etc., all as will hereinafter more fully appear.

In the accompanying'drawings: Figure 1, is a front elevation of the scaffolding. 2, is an end elevation of the same. Fig. 3, 1s a detail perspective view of a base member or footing and its accessories, the parts be ing shown partly detached. Fig. 4, is a similar view of an intermediate coupling member of the structure, with the vertical post removed. Fig. 5 is a similar view of a Fig. 6, is a detail perspective view of the inner portion of.the balcony frame. Fig. 7, is a similar view of railing connection of the balcony:

frame.

Similar reference numerals indicate like parts in the several vlews.

Referring to the drawings, 1 designates a series of base members or footings adapted 'to rest upon the ground or other supporting surface, and 2 designates a series of intermediate members or couplings of the structure. Said members 1 and 2 are connected inpairs by transverse tiebars 3, and are adapted for ready coupling with the adjacent ends of the posts or uprights 4 of the structure, as well as to the series of diagonal bracing members 5, thereof,-and to such end each base member or footing 1, will have a detail structure as follows! 6 designates a horizontal bottom plate forming the support of an upright longitudinally disposed gusset plate 7 and for a pair of spaced cheek plates 8, which are secured to the bottom plate 6 by angle-brackets 9 and rivets or like fastening means.

I The space between the cheek plates 8, is

adapted to receive a vertical web of an adstructure, which, is riveted or bolted in place between the cheek plates asshown. Said space is-al'so adapted to receive the vertical soiletdmember now to be described.

ates a vertical socket member jacent ,endof a transverse tie bar 3 of the i having a ower flattened or'pla'te like po'r- I tion adapted to fit the aforesaid space betweenthe cheek plates 8 and be bolted or riveted in place as shown. Said socket mem-" her 10 is preferably formed from a section of metal tubing flattened at its lower end,

' with its rounded upper end adapted to receive a reduced cylindrical stud or extension 11, formed to fit within the lower end of a tubular post or upright 4: of the structure, to provide a substantial coupling of the parts. 12 deslgnates transverse ori ces formed in the gusset plate 7, for the passage of bolts or rivets by which adjacent ends of the dia onal bracing members 5 are attached to said gusset plate.

The intermediate or coupling members 2 have a detail construction as .follows:

13 designates-a longitudinally disposed upright gusset plate formed with a series of transverse orifices 14 for the passage of bolts or rivets by which adjacent ends of diagonal bracing. members 5 are attached to the gusset plate.

15 designates a pair of transversely ar V ranged cheek plates secured to the gusset abutment or stop for an individual hinged transverse tie bar 3, hereinafter described.

The transverse tie bar 3 which connects a pair of the intermediate members 2' together,

is preferably formed of T shaped structural iron, the vertical web portion of which is fitted into the space between the cheek plates 15 above the filler piece 16, and'is pivotally secured in place at a pointoutside said filler piece by a pivot bolt or rivet 17, as shown.

'18 designates alined orifices formed in the of the tie bar 3 at a point inside the filler piece 16, and adapted to-rec'eive a locking pin 19, for locking the parts to ether in assembled relation. The describ connecpair of cheek plates 15 and in the vertical web tion of a pair of members 2 is adapted to admit of. a compact folding together of the parts, and. at the same time provide a strong and rigid structure when erected for use.

The post 4. which is associated with a member 2, is formed with an intermediate flattened or platelike portion adapted to fit within the space between the cheek plates 15 and be bolted or riveted inplace as shown. Said post 4 is preferably formed of tubing with its rounded upper end provided with a reduced cylindrical stud or extension 20 formed to fit within the lower end of an adjacent tubular post of the structure, in manner similar to that described in connection with the base member or footing 1, aforesaid.

v to such end the length of the posts or up- The construction described provides for the erection of a wall scaffolding of any height, and with the series of floors which are supported on the transverse tie bars 3, at the required vertical distances apart, and

rights 4 will be varied to suit.

21 designates a series of horizontal balcony forming rails, preferably of angle-iron as shown, and having at their inner ends flanged plates 22 by which they are bolted to adjacent gusset lates 13 of the structure.

23 designates a racket plate secured to an outer end of a balcony rail 21, and providing means for the attachment of the following parts :-24 designates a diagonal brace secured at one end to the bracket plate I 23, and attached at its other end to a post or upright 4 of the structure by a clevis bolt 25, as shown. 26 designates a socket bracket secured tothe bracket plate 23 and adapted in conjunction with an alined orifice 27 in the horizontal web of the balcony rail 21, to form a receiving socket for one of the posts 28 of a railing arranged at the outer edge of the balcony. The railing referred to will preferably comprise a series of the posts 28 carrying a rail or guard rope at their upper ends, as illustrated in Fig. 2.

29 designates a vertical tie bar connecting the inner portion of a balcony rail with an inner portion of the diagonal brace 24 and adapted to prevent vertical movement of the innate -the combination of a gusset plate adapted for the attachment of diagonal braces of the structure, a pair of cheek plates fixedly secured to said gusset plate in spaced relation to each other and 1n right-angle relation to said gusset plate, a horizontal rail havmg a vertical Web, the end of which is fitted and secured between the cheek plates aforesaid, and a tubular post having a flattened portion which is fitted and secured between said check plates, substantially as set forth.

2. In a scaffolding of the type described, the combination of a gusset plate adapted for the attachment of diagonal braces of the structure, a pairof cheek plates fixedly secured to said gusset plate in spaced relation to each other and inIright-angle relation to said gusset plate, a filler piece secured between said check plates to constitute a stop, a horizontal 'rail having a' vertical web, the end of which is pivotally secured between the cheek plates aforesaid, and a tubular post having a flattened portion which is fitted and secured between said cheek plates, substantially as set forth.

3. In a scaflolding of the type described, the combination-of a sset plate adapted for the attachment of diagonal braces of the structure, a pair of cheek plates fixedly secured to said gusset plate-in spaced relation to each other and in right-angle relation to said gusset plate, a base plate fixedly secured to gusset plate and to the cheek plates WILLIAM w.
